The Definition of Long Colt
Although a misused term (even within the firearms industry), Long Colt is a designation for an ammunition cartrige developed by Colt mainly used for revolvers. The actual designation is Colt instead of Long Colt.
The term Long Colt was originally coined to avoid confusion between the .45 Colt and .45 ACP cartridges

National Firearms Act of 1934.
Enacted on June 26, 1934, currently codified as amended as I.R.C. ch. 53, is an Act of Congress in the United States that, in general, imposes
a statutory excise tax on the manufacture and transfer of certain firearms and mandates the registration of those firearms.
The Act was passed shortly after the repeal of Prohibition. The NFA is also referred to as Title II of the Federal firearms laws.

- Requires the registration of all fully automatic firearms.
- Requires the registration of all "sawed off" rifles and shotguns.
- Requires the registration of firearm silencers.
- Imposes a $200 transfer tax on the above items.
Is that combination of caliber, barrel length, bullet weight, and case volume which does not
allow the complete burning of the charge of ballistically correct powder within the volume of case and barrel.
A small orifice at the breech end of the barrel of a muzzle-loading firearm through which the exploding priming charge is conducted from the flash pan to the main charge.
The recoil spring is the powerful spring that cushions the slide in its rearward travel and then sends the slide forward again with enough force to drive the fresh round firmly into the chamber.
The strength of the recoil spring is calibrated to run the slide without any outside assistance.
A catch built into the receiver of a break-open gun to keep the toplever in its extreme right position when the barrels are removed.
This device makes it slightly easier to remount the barrels. As the barrels are mounted and the breech closed,
the barrels contact some kind of release pin (marked with the arrow) and the toplever automatically returns
to the center locked position. Because, however, it requires a separate act to find and to depress this tiny
tab to re-center the toplever on a broken-down gun, this feature may be irritating when trying to put a gun away in its case.
The action of an external hammer pinching or poking the web of the operator's
shooting hand between the thumb and fore-finger when the gun is fired.
A three-barrel gun.
Typically it has two shotgun barrels side by side on the top, with a third rifle barrel underneath.
This provides a very versatile firearm capable of taking winged animals as well as big game.
It also is useful in jurisdictions where a person is only allowed to own a single firearm.
Typically used in the .22 caliber cartridge designation .22 Long Rifle, which is abbreviated .22LR.
A shotgun with two barrels, usually of the same gauge or bore.
The two types of double-barreled shotguns are over/under (abbreviated as O/U or OU),
in which the two barrels are stacked on top of each other, and side-by-side (abbreviated as SxS),
in which the two barrels sit beside each other. See photo at right for example of side-by-side double-barreled shotgun.
For double-barreled guns that use one shotgun barrel and one rifle barrel, see combination gun.
A shotgun, generally stocked to shoot where it is pointed and of relatively light weight because one often carries it a great distance for upland birds,
the consequent recoil not being an important factor because one actually shoots it very little.
The official US military designation for the Colt .45 semiautomatic pistol adopted by the US in 1911.
The gun was designed by John Moses Browning, and produced by Colt.
During trials, the Browning-Colt design beat out several competing designs, including one from Savage and a .45 caliber version of the German Parabellum ("Luger").
The M1911 saw its first combat in the Philippines and then in World War I.
Early use showed that it could be improved and in 1921 the M1911A1 was introduced, which featured a few changes like a reocontoured frame,
shorter trigger, and a rounded backstrap. The M1911A1 remained the standard US military handgun until it was replaced in the 1980's by the Beretta M9.
However, it remains very popular with civilian shooters in the US, and has been modified extensively to update it to
conform to more modern theories of handgun usage.
A type of mechanism for removing a spent shell casing from the chamber of a firearm and inserting a fresh cartridge into the chamber.
This type of mechanism is most commonly used in shotguns and rimfire rifles.
Any malfunction that results in no shot fired when the trigger is pulled. Commonly caused by a failure to feed, bad ammunition or a broken firing pin.
